(origin of the word) The word female comes from the Latin femella, the diminutive form of femina, meaning "woman"
(def of woman) A woman is an adult female human.
Female is most commonly an adjective. It can be used as a noun as a shorthand (for female person e.g.), but outside of technical contexts it's dehumanizing.
It's fine to use if you're saying both males and females, although it's weird in casual speech and people will likely assume you have some personal reason to not use 'women' instead.
There are people who say 'men' and 'females', which betrays a dehumanizing attitude towards one group over the other.
Without people with that attitude around, it's just awkward to refer to people as males and females outside of technical discussion. With people who have that attitude around, talking in the same way makes you seem really sus. Which is not necessarily fair.
